It'll depend on the track. Both have their strong points. On Sebring they are about equal on the long course but in my experience the ITR can get a bit quicker on the 'club course'.. but then it wasn't the same driver so :shrug:. I've passed modified 3rd gens in my GS-R before too though, so driver experience/etc is going to play a part in any 'real world' comparison.

Personally, I like the 3rd gen more for a track car, but then I don't care much for FWD anyways..
